Surgical needle

Disclosed are sterile surgical needles formed of alloys of tungsten and a second metal selected from the group consisting of rhenium, rhodium and iridium. The needles exhibit a tensile yield strength in excess of 250,000 psi and a tensile modulus of elasticity in excess of 45 x 10 psi, and have adva...

Zusammenfassung:Disclosed are sterile surgical needles formed of alloys of tungsten and a second metal selected from the group consisting of rhenium, rhodium and iridium. The needles exhibit a tensile yield strength in excess of 250,000 psi and a tensile modulus of elasticity in excess of 45 x 10 psi, and have advantageously high ductility.
